Hello all,Iv"e got a worcester/bosch 280 combi boiler.Bit strange to me but,when the central heating is off,and hot water on,im getting no hot water through taps,but the upstairs radiators are hot? Turnred boiler off at mains for day ,then back on and now ive got hot water through taps but upstairs radiators heating up also.Anyone had this problem,or got any ideas ? Thanks in advance
